Abstract

To develop a tool to analyze stability and design compensators that damp voltage oscillations in a power distribution system, we devised, taking into account the diode rectifier and the IGBT/GTO inverter, a control scheme so that the motor is seen as a passive load by the network. This property is obtained for the error signals (voltage, current) resulting from perturbations. For a constant rotor speed set point, a rotor flux trajectory has been computed for the system to satisfy the passivity definition and to guarantee the signal boundedness and asymptotic stability for the rotor flux and speed
